| 摘 要： | 传统的光伏电池最大功率点跟踪(MPPT)技术需要同时检测光伏电池的输出电压和输出电流2个变量,在传统的电导增量法的基础上提出一种新的MPPT算法,该算法通过Boost变换器实现系统的MPPT。与传统算法相比,新算法只需检测光伏电池的输出电流,通过调节变换器的占空比,实现光伏电池阵列的输出功率最大化,减少了光伏系统的成本。仿真结果验证了该方案的正确性和可行性。

| Abstract: | The traditional MPPT(Maximum Power Point Tracking) technology for photovoltaic cells has to detect the output voltage and output current.An MPPT algorithm based on traditional incremental conductance method is proposed for Boost converter,compared with the traditional algorithm,which only detects the output current of photovoltaic cell to achieve the maximum power output by adjusting the duty cycle of Boost converter and reduce the cost of photovoltaic system.Its correctness and feasibility are verified by the simulative results. |
